142. Solving a chemistry problem

3.16. Calculate the particle size of AgCl in acetone if the settling time in the centrifuge was 8 minutes under the following conditions: initial level h1 = 0.05 m; final level h2 = 0.10 m; the density of the dispersed phase p = 5.6 * 10 ^ 3 kg / m3; the density of the dispersion medium p0 = 0.79 * 10 ^ 3 kg / m3; viscosity n = 0.33 * 10–3 Pa * s; centrifuge rotation speed n = 1800 rpm
